Question

If 7sinA+24cosA=25,prove that cotA=24/7​

Answer 1

Answer:

1

Step-by-step explanation:

Sec^2 A - tan^2 A / (sin^2 A + cos^2 A) considering this as the question then using trigonometric identities

Sin^2 A + Cos^2 A = 1

Sec^2 A - Tan^2 A = 1

This implies sec^2 A - tan^2 A /(1)

This give sec^2 A - tan^2 A = 1
